A Study on Establishing a "Critical State" Early Warning Score After Congenital Heart Disease Surgery and an Integrated Treatment Model of a Multidisciplinary Rapid Response Team

All children aged 0-14 years admitted to the PICU from 2021-2022 were enrolled continuously, and their baseline data such as gender, age, RACHS-1 score, cardiopulmonary bypass time, aortic clamping time, whether there was chromosomal lesions, whether there was preoperative endotracheal intubation/heart failure, changes in oxygenation index, lactate, and vasoactive drug scores were obtained. All variables that may lead to composite malignant events including death in the early postoperative period were included, including death, pulmonary hypertension crisis, malignant arrhythmias (supraventricular tachycardia, ventricular tachycardia, ventricular fibrillation, high-degree atrioventricular block) requiring antiarrhythmic drugs or pacemaker treatment, cardiopulmonary resuscitation, ECPR, emergency sternal expansion, severe AKI, severe ARDS, neurological complications (cerebral hemorrhage, cerebral infarction), gastrointestinal complications (gastrointestinal bleeding, intestinal obstruction, intestinal necrosis).The variables were included in the machine learning analysis to establish the model.
